Hello everyone!
I'm relatively a Ladybug newbie, so sorry if might seem a fool question, but i really need to solve this problem...
I'm working on an architectural project for Tokyo, specifically investigating wind direction and speed on site. I managed to work with LB wind rose and wind profile components, but i don't understand why the Tokyo epw file downloaded from Onebuilding (meteo station 476620) displays the wind like it comes from 180° degrees (south) for every hour in every day of the year! Looks like it is actually an inherent problem of this specific epw data, because using Tokyo- Hyakuri, epw data, produces a realistic wind rose instead.
I know i just could use the tokyo hyakuri file, but the actual distance of Hyakuri aeroportual meteo station from Tokyo area seems really too much for a realistic analysis! (100 km north from Tokyo, more or less).
Any hint on the origin of this probably "corrupted" wind direction values?
Found the same .epw file at 40 $ downloadable on this site http://weather.whiteboxtechnologies.com/IWEC2
Think would be worth buying the file elsewhere? Maybe data is corrupted only for onebuilding portal?
